Hi all !
I got confused with set and get attributes in HttpSession interface. Please see the below attached program:

Here its working fine but if i change date to date1 in getAttribute its showing error but if i write as
Date date=new Date(); then if i change date to date1 in getAttribute its not showing error . Why so ?

Thanks & Regards
Kori Swapna Latha.

Hi Latha,

Before you post the java code , use code tag. Because it is used to easy view your code.

Do you mean if you change line 34 from date = new Date(); to Date date = new Date();? You're then trying to declare a new variable with the same name as an existing variable (the one you declare on line 29).

if(date1!=null)\{
.........
}
date=new Date();
..............
................

You have created the date1 variable and assigning the session date object to it.

But in the next line you are creating a new date object and assiging to the "date" variable but the variable is not even created.
Try Date date = new Date();
